Subject [jira] [Commented] (HBASE-8015) Support for Namespaces
Date Thu, 07 Mar 2013 19:32:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13596250#comment-13596250

Enis Soztutar commented on HBASE-8015:
--------------------------------------

bq. I've also changed the tableDir on hdfs to include namespace as the parent directory
How do you plan to enforce this? WAL's completely bypass the quota, and if a ns's quota fills
up, it cannot flush, and compact, which will affect all of the other namespaces. I am not
against the idea of having a parent namespace dir for tables, but just wondering whether this
is really feasible. Can't we enforce quotas at the HBase level, since we are doing ACL's at
the application layer for the same reasons.
